Error Description and Repair Action
Ground but no ringing. This error occurs on an incoming call on a
ground-start trunk. If ringing is not detected within 5 seconds of the Tip
being grounded, the call is still accepted. If the CO is of the No. 5ESS.
switch type, ringing delays of more than 5 seconds during heavy traffic
are fairly common. Check for other errors.
The loop is opening too slowly after a disconnect. This error indicates an
on-board problem, although the trunk may be functional. Check for other
errors.
No loop current on incoming call. The incoming destination has already
answered and no loop current has been detected. If this is a hard fault, the
dial tone test and all outgoing calls should also fail. Check for other
errors.
Trunk error. No Tip ground detected on outgoing call. This error occurs
when an attempt is made to seize a ground-start CO trunk for an
outgoing call and Tip ground is not detected or the caller hangs up before
Tip ground is detected.
Busyout the affected port, and run a long test. Observe the test results. If
any tests fail, refer to the description of the tests and the associated error
codes. Release the port.
If users continue to report troubles, check for other errors and make test
calls to determine whether the problem should be referred to the CO.
Busyout the affected port, and run a long test. If Dial Tone Test #0
passes, ignore this error. Release the port.
No loop current on outgoing call. This error occurs on attempt to seize a
loop or ground-start trunk for an outgoing call. An error occurs if loop
current is not detected or the caller hangs up before it is detected.
Busyout the affected port, and run a long test. If CO Demand Diagnostic
Test #3 passes and this error keeps occurring, refer problems to CO.
Release the port.
